Kīla

thumb|Phurba in the Walters Art Museum The phurba (; alternate transliterations: phurpa, phurbu, purbha, or phurpu)or kīla (Sanskrit Devanagari: कील; IAST: kīla) is a three-sided peg, stake, knife, or nail-like ritual implement deeply rooted in Indo-Tibetan Buddhism and Bön traditions. Its primary association is with the meditational deity Vajrakīlaya (Dorje Phurba), embodying the essence of transformative power. The etymology and historical context of the term reveal some debate. Both the Sanskrit word kīla and the Tibetan phurba are used interchangeably in sources.

The construction of the phurba is diverse, featuring a pommel, handle, and a blade with three triangular facets. The composition often revolves around the numerological significance of three and nine, with materials ranging from wood and metal to bone and crystal. Phurba blades can be made from meteoric iron, which holds symbolic importance. The pommel typically displays faces of Vajrakīlaya or other sacred motifs. This implement is not intended as a physical weapon, but rather as a spiritual tool, embodying stability and energetic continuity.
